Compact 40 mm CPU fan

The OEM Industries CF-12407S is a 40 mm square cooling fan designed for small-form-factor CPU air coolers. It runs on 12 V at 0.14 A and uses a two-pin power connector, making it a direct replacement for low-profile heatsinks that need a slim 7 mm thick fan. Buyers who need higher airflow or PWM speed control will not find those features here.

Sleeve bearing and fixed-speed wiring

A sleeve bearing keeps the fan running quietly at constant voltage, while the two-pin lead means speed is set by the motherboard voltage rather than a PWM signal. The 40 mm frame and 7 mm depth fit tight clearances around socket keep-out zones, but the lack of a third wire prevents automatic fan-curve adjustments that some builders prefer.

Basic two-wire connection only

The package supplies the fan itself with its pre-attached two-wire lead; no mounting screws, adapters or software utilities are included. Installers must provide their own fasteners and rely on the motherboard header for power, so anyone expecting a complete mounting kit or RGB lighting will need to source those separately.

Questions about this item

What does the 2-pin 12V .14A connector limit for fan control?

The 2-pin 12V 0.14A connector supplies fixed voltage, so speed cannot be adjusted by PWM or voltage regulation from the motherboard header.

Will the 40mm square frame with 7mm thickness fit my mounting holes?

The fan measures 40mm square and 7mm thick; verify your heatsink or chassis has matching 40mm hole spacing and clearance for the 7mm depth.

How do I connect the two wires correctly on first install?

Connect the red wire to the 12V pin and the black wire to ground on the 2-pin header; reversing them will prevent the fan from spinning.
